Figure 2

Biplot (separation) based on morphometric data of Pratylenchus araucensis populations. Populations of P. araucensis from Caldas, Quindío, and Valle del Cauca were assigned to their corresponding species based on morphometric data. The first two PCA axes are shown. Pa = Pratylenchus araucensis, Ara = Arauca, Cal = Caldas, CoQ = Quindío, ZaB = Zabaletas (Valle del Cauca [Buenaventura]), and DelB = Delfina (Valle del Cauca [Buenaventura]). PCA, principal component analysis.
